WEEX Crypto News, 17 April 2026
The recent eruption of hacks in the decentralized finance (DeFi) landscape is a stark reminder of the vulnerabilities inherent in this nascent sector. On April 1, 2026, the largest decentralized perpetual futures exchange on Solana, Drift Protocol, fell victim to a sophisticated attack. In a matter of minutes, attackers siphoned off approximately $280 million in user assets. This exploit involved the creation of a non-existent asset, the CarbonVote Token, which was manipulated through wash trading to appear as legitimate collateral. This audacious heist set the stage for a series of attacks that have rocked the DeFi community.
Following the Drift Protocol breach, a spate of cyberattacks has unfolded, targeting no fewer than 12 additional crypto entities. Among the affected platforms are CoW Swap, Hyperbridge, Bybit, and Dango. Most notably, Rhea Finance and the Grinex exchange have suffered significant losses in recent days, losing approximately $7.6 million and $13.7 million respectively. Investigations reveal that the Rhea Finance hack involved a vulnerability in the margin trading functionality, which was exploited to manipulate their smart contract pool.
DeFi security experts and platforms such as DeFiLlama report that the first quarter of 2026 alone has seen malicious actors steal over $168.6 million through various hacks across 34 protocols. The scale and sophistication of these attacks highlight the critical need for enhanced security measures and robust response strategies within the DeFi sector.
Security analysis indicates that the hack on Drift Protocol was part of an elaborate, months-long North Korean intelligence operation. Posing as a legitimate trading firm, the attackers embedded themselves deeply within the Drift community, building trust over six months before executing their plan. Utilizing complex social engineering tactics and vulnerabilities in security standards, the operation exposed serious weaknesses in the DeFi community’s reliance on multisig-based security models.
The wave of recent hacks underscores the importance of innovation in security strategies to safeguard user assets against such sophisticated threats. As these developments unfold, platforms like WEEX are committed to navigating the highs and lows of the crypto markets.

Mixin has launched USTD-margined perpetual contracts, bringing derivative trading into the chat scene.
The privacy-focused crypto wallet Mixin announced today the launch of its U-based perpetual contract (a derivative priced in USDT). Unlike traditional exchanges, Mixin has taken a new approach by "liberating" derivative trading from isolated matching engines and embedding it into the instant messaging environment.
Users can directly open positions within the app with leverage of up to 200x, while sharing positions, discussing strategies, and copy trading within private communities. Trading, social interaction, and asset management are integrated into the same interface.
Based on its non-custodial architecture, Mixin has eliminated friction from the traditional onboarding process, allowing users to participate in perpetual contract trading without identity verification.
The trading process has been streamlined into five steps:
· Choose the trading asset
· Select long or short
· Input position size and leverage
· Confirm order details
· Confirm and open the position
The interface provides real-time visualization of price, position, and profit and loss (PnL), allowing users to complete trades without switching between multiple modules.
Mixin has directly integrated social features into the derivative trading environment. Users can create private trading communities and interact around real-time positions:
· End-to-end encrypted private groups supporting up to 1024 members
· End-to-end encrypted voice communication
· One-click position sharing
· One-click trade copying
On the execution side, Mixin aggregates liquidity from multiple sources and accesses decentralized protocol and external market liquidity through a unified trading interface.
By combining social interaction with trade execution, Mixin enables users to collaborate, share, and execute trading strategies instantly within the same environment.
Mixin has also introduced a referral incentive system based on trading behavior:
· Users can join with an invite code
· Up to 60% of trading fees as referral rewards
· Incentive mechanism designed for long-term, sustainable earnings
This model aims to drive user-driven network expansion and organic growth.
Mixin's derivative transactions are built on top of its existing self-custody wallet infrastructure, with core features including:
· Separation of transaction account and asset storage
· User full control over assets
· Platform does not custody user funds
· Built-in privacy mechanisms to reduce data exposure
The system aims to strike a balance between transaction efficiency, asset security, and privacy protection.
Against the background of perpetual contracts becoming a mainstream trading tool, Mixin is exploring a different development direction by lowering barriers, enhancing social and privacy attributes.
The platform does not only view transactions as execution actions but positions them as a networked activity: transactions have social attributes, strategies can be shared, and relationships between individuals also become part of the financial system.
Mixin's design is based on a user-initiated, user-controlled model. The platform neither custodies assets nor executes transactions on behalf of users.
This model aligns with a statement issued by the U.S. Securities and Exchange Commission (SEC) on April 13, 2026, titled "Staff Statement on Whether Partial User Interface Used in Preparing Cryptocurrency Securities Transactions May Require Broker-Dealer Registration."
The statement indicates that, under the premise where transactions are entirely initiated and controlled by users, non-custodial service providers that offer neutral interfaces may not need to register as broker-dealers or exchanges.
Mixin is a decentralized, self-custodial privacy wallet designed to provide secure and efficient digital asset management services.
Its core capabilities include:
· Aggregation: integrating multi-chain assets and routing between different transaction paths to simplify user operations
· High liquidity access: connecting to various liquidity sources, including decentralized protocols and external markets
· Decentralization: achieving full user control over assets without relying on custodial intermediaries
· Privacy protection: safeguarding assets and data through MPC, CryptoNote, and end-to-end encrypted communication
Mixin has been in operation for over 8 years, supporting over 40 blockchains and more than 10,000 assets, with a global user base exceeding 10 million and an on-chain self-custodied asset scale of over $1 billion.
